I need DTS to survive, which edition of SQL Server 2005 should I buy?

I heard about SSIS, a new replacement of the old DTS. I believe it has the same functionality which I used to perform. Now, like any other product from Microsoft, you have to mess with 10 different choices for a single package. I would like to get your opinion of which edition of SQL Server 2005 I should buy to ensure that I can replica...

What is the lowest SQL Server 2005 edition to support SSIS?

thanks in advance. ...
